geez dvefussner's looks like one of my blinds. I almost thought it was pic of it. Mine sits on a ridge like that and everything.
Anyway I agree except I would add the tried and tested method of sticking evergreen branches like spurce or cedar in as well. You take that blind in dve's pic and stick some evergreen branches up out of the windfall he's stacked up and you are in a great set up.
A tip from AJH I've usd is to just do this with branches around you as well. You push the trimeed off evergreen branches into the ground around you. You can have great concealement and breakup in about 5 mins when on the move. I think my garden snips is one of the most important things in my vest. If I could only take the absolute min it would be gun, 2 shells, my tag, one mouth call and a pair of snips.
